Actinides are a part of the periodic table wtih atomic numbers of 89-103. They are listed in order below. ·Actinium (Ac) 89 ·Thorium (Th) 90 ·Protactinium (Pa) 91 ·Uranium (U) 92 ·Neptunium (Np) 93 ·Plutonium (Pu) 94 ·Americium (Am) 95 ·Curium (Cm) 96 ·Berkelium (Bk) 97 ·Californium (Cf) 98 ·Einsteinium (Es) 99 ·Fermium (Fm) 100 ·Mendelevium (Md) 101 ·Nobelium (No) 102 ·Lawrencium (Lr) 103
uranium
These elements are a part of Period 7 they are between groups 2 and 3.
The first four of the elements are Solids and the rest aren't found in nature.
Three physical properties of actinides are:
They have a high density
They have a crystalling structure
They are colorful (purple, pink, red, green, etc.)
Three chemical properties are:
Reacts with water
Reacts with air
Reacts with acids
However they do not react with bases
Actinium
Two common uses for these elements are:
It can be used for cancer therapy by destroying the cancerous cells by radioactivity
Creating atomic energy in power plants the nuclear reactions create electric energy
Although, the only the only actinides found on earth's crust in appreciable quantities are thorium and uranium. However small amounts of plutonium and neptunium have been found in uranium ores.
Three interesting facts about actinides are:
The first atom bomb that was created used the explosive power of Uranium and Plutonium. The atom bomb that was releaed over Japan was the first uranium bomb released.
Plutonium is one of the most complex elements on the table of elements because depending on the temperature it can take on 6 different forms each with a different volume and density. This makes it very hard for scientists to run tests on it because it is highly dangerous and toxic. While other metals have undergone extensive characterization tests, plutonium has not been able to study do to its many forms that are periodically changing.
The Department of Energy gives $100 million dollars a year for further research on actinides. They do this to better understand the long-term effects of these radioactive elements.
